Patented Dec. 17, 1929 CHRISTIAN J. KAISER, OF GREAT FALLS, MONTANA VENTILATED TOILET BOWL Application filed December 18, 1928.

This invention relates to closet bowls and more particularly to devices of this character having means embodied therein for ventilating same.

One of the objects of this invention is to provide, in a manner as hereinafter set forth, a device of the aforementioned character having inherent means for thoroughly ventilating the interior of the bowl from beneath the vention will be apparent from a study of the accompanying drawings, taken in connection with the following specification.

In the drawings, wherein like characters of reference designate corresponding parts throughout the several views Figure 1 is a top plan, partly in section, of a bowl constructed in accordance with this invention.

Figure 2 is a bottom sectional plan taken on the line 2-2 of Figure 3.

Figure 3 is a longitudinal section of the bowl wherein same is shown connected to a flushing tank and a vent pipe.

Referring to the drawings in detail, reference character 1 designates the body portion of a closet bowl of the conventional type and which is provided with an outlet passage 2. The upper portion of the bowl 1 is provided, near its rear end, with a water receiving chamber 3 into which water flows from the flushing tank 4 through a conduit 5. At a point below its upper edge the bowl 1 is provided with a substantially annular water conducting channel 6. The channel 6 communicates with the interior of the bowl 1 for its entire length by means of a continuous opening 7 provided by the lip portion 8 of said bowl in connection with the opposed spaced Serial N0. 326,830.

body portion thereof. Preferably the opening 7 is approximately one-eighth of an inch in width. The channel 6 communicates, at its opposite ends, with the chamber 3 near the forward end of said chamber and on its opposite side. V

Projecting rearwardlyfrom the chamber 3, the bowl 1 is provided with an integral extension 10. An outlet recess 11 is formed in the extension 10 rearwardly of the Water receiving chamber 3. Communicating with the recess 11, on its opposite sides, area pair of air passages 12 which extend longitudinally through a portion of the upper part of the bowl 1 on oppositesides of the water chamber 3. The passages 12 are formed in the bowl 1 above the horizontal plane of channel 6. On its inner circumference and at the rear thereof, the upper portion of the bowl 1 is provided with an integral arcuate ledge 13 into which thepassages 12 extend longitudinally and communicate with the interior of the bowl through spaced openings 14 formed 1n the lower face of the ledge. A vent pipe 15 communicates with the outlet recess 11 through the coupling pipe 16. It will be noted that recess 11 constitutes a common outlet for passages 12.

Intermediate the openings 14;, the ledge is provided with an integral, downwardly d1- rectecl tongue 17 which extends below the bottom of chamber 3 and terminates in opposed, spaced relation to the adjacent interior surface of the bowl 1 in a manner'to form a discharge opening 18. The tongue 17 forms the forward wall of chamber 3 and constitutes a deflector for directing the water which flows through the discharge opening 18 of chamber 3, downwardly against the inner surface of the bowl at the rear thereof.

Inuse the bowl 1 is ventilated through openings 14:, passages 12, outlet 11, coupling pipe 16 and vent pipe 15. When the bowl is flushed, the water, entering chamber 3 through pipe 5 from tank 4;, is directed downwardly into the bowl through the opening 18 formed between the tongue 17 and the adj acent portion of said bowl. It will, of course, be understood that solne of the water which enters chamber 3 passes into the channel 6 Which conducts same around the bowl and discharges it in a sheet-like manner through opening 7 against the entire inner surface of said bowl, resulting in a more thoroughly washed bowl than if the water were discharged thereinto through a series of small openings, as is usual By this arrangement of the openings. I4: and passages 12 it is impossible for the ventilating structure to interfere with the proper functioning of the flushing" mechanism, or' vice versa. In addition to this, theinovel 3J3. rangement of the ventilating means renders the openings 14 invisible;

15 It is believed that the many advantages of a closet bowl constructed in: accordance: with thisinvention-.willzbereadily understood, and although the: preferred embodiment of the" invention is as: illustrated? and. described, it is m. to beamderstood that changesainzthe cletailszof construction may be had which will fallwsithinrthe scope otthe: appended claim.

What I claim ism- A closet bowl being-t provided with a water receiving chamberand a' water conducting channel communicating with said chamber: andithe'interior at the bowl. an arcuate ledge: formed on" the! interior of said bowl above: the horizontal plane of. the' channel and: at the 3'01- rear" thereof and. having its opposite ends merging into the: adjacent: sides oii the channel, a water deflecting: tonguev carried. by the ledge: intermediate its: ends, extending, downwarcl ly'below the bottom of the chamber at a 33? point forwardly oii same, said ledge constitutingthe forward wall: of said chamber, and, in: conjunction; with the adjacent wall: of the bowl, providingian outlet therefrom; directly into said bowl, said bowl being further: pro

40 viidedlwith vent passages disposed on opp0- site sides oiithe chamber abovethehorizontaP plane ct the-channel, said. passages: leading to a common outlet at the rear 01: the bowl; and: each: having its. forward end provided: with ;v an elongated. vent opening on the'under' side;

of the ledge on opposite side of the: deflecting tongue.

In testimony whereof, I affix my signaturehereto.
